I am in the process of configuring a Dell MD3260 Storage Array for a DPM 2012 storage pool and I am not sure what the best RAID configuration is to choose. The array has a capacity of 90Tb and this needs to be split between 2 DPM servers that will need to backup to their own separate LUNs.
If anyone has any advice on either of the 2 following questions it would be much appreciated:
1. Which RAID configuration I should choose?
2. Should I have several small disk groups or one large one to improve performance?
Thanks
Chris
